It was discovered that the Transmission web interface was vulnerable to
cross-site request forgery (CSRF) attacks. If a user were tricked into
opening a specially crafted web page in a browser while Transmission was
running, an attacker could trigger commands in Transmission. This issue
affected Ubuntu 9.04. (CVE-2009-1757)
Dan Rosenberg discovered that Transmission did not properly perform input
validation when processing torrent files. If a user were tricked into
opening a crafted torrent file, an attacker could overwrite files via
directory traversal. (CVE-2010-0012)
